Build on ARC with EVM tools
ARC supports familiar Solidity and EVM tooling such as ethers and viem, but developers must account for ARC-specific behavior including USDC gas precision, native and ERC-20 USDC interfaces, transaction extensions and restricted-transfer reverts.

How XPayr applies it
XPayr validates chain IDs, token decimals, contract bytecode and signed payload boundaries before enabling a route. Developer pages link the ARC primitive to checkout sessions, webhook records and non-custodial wallet execution.
Verified on ARC Testnet
XPayr keeps ARC Mainnet payment execution review-gated until canonical production contracts, explorer support and low-value wallet-signed pilots are verified. Public tools and Testnet flows remain available for evaluation.
From question to a controlled ARC transaction
Understand the primitive
Start with the exact ARC capability, supported asset and network boundary instead of a generic blockchain promise.
Plan the route
Choose checkout, send, bridge, swap, Unified Balance, memo, batch or agent settlement and review its fee model.
Sign from the wallet
The merchant or payer wallet signs the operation. XPayr does not treat a browser response as settlement proof.
Verify and reconcile
XPayr checks chain, token, amount, recipient and transaction evidence before updating payment and fee ledgers.

Is this available on ARC Mainnet through XPayr?
XPayr keeps ARC Mainnet payment execution review-gated until canonical production contracts, explorer support and low-value wallet-signed pilots are verified. Public tools and Testnet flows remain available for evaluation.
Does XPayr custody funds or hide the network fee?
No. Wallets sign transactions, chain fees remain visible and XPayr records its operation fee separately. Standard successful checkout uses the configured XPayr gateway fee; advanced ARC operations use their published fee quote.

What is ARC?
ARC is an EVM-compatible Layer 1 built for programmable money. It uses USDC as its native gas token, targets sub-second deterministic finality and integrates Circle infrastructure for payments, liquidity and crosschain movement.
Verified on ARC TestnetARC transaction memos
ARC Memo attaches structured metadata to a contract call and emits an indexed event. Payment IDs, invoice references, payout batches and operational notes can therefore travel with auditable onchain evidence instead of an offchain screenshot.
Verified on ARC TestnetARC security and opt-in privacy
ARC documents configurable privacy and post-quantum security as evolving parts of its roadmap. Current integrations should distinguish live execution behavior from planned protocol modules and preserve auditability where regulations or operations require it.
